Description

The Yeastar B2 Module is a modular telephony accessory designed to add 2 ISDN BRI ports to compatible Yeastar IP PBX systems. It is a key component in Yeastar’s modular design philosophy, enabling businesses to seamlessly integrate their modern VoIP infrastructure with traditional ISDN (Integrated Services Digital Network) Basic Rate Interface (BRI) lines.

The B2 Module is a compact circuit board that plugs directly into a dedicated module slot on various Yeastar S-Series and P-Series PBX systems. An ISDN BRI port provides two digital channels (2B+D), allowing for up to two simultaneous voice calls or one data call, such as for a video conference. This functionality is essential for businesses that rely on legacy ISDN services for their primary telephone lines or for a backup communication channel.

The “plug-and-play” nature of the B2 Module makes installation simple and straightforward. Once the module is inserted into the PBX’s chassis, the system automatically detects the new ports, which can then be configured through the PBX’s intuitive web-based management interface. This eliminates the need for complex rewiring or a full system replacement when a business needs to add BRI connectivity.

The B2 Module is a critical component for businesses that are in a gradual transition from ISDN to VoIP. It allows them to preserve their investment in ISDN lines, phone numbers, and services while benefiting from the reduced costs and advanced features of an IP PBX. The module also serves as a reliable failover option, ensuring business continuity in the event of an internet or VoIP service outage by automatically routing calls over the ISDN lines.
